While chatting with fans about his new movie, The Monuments Men, George Clooney spilled the beans on many of his famous friends and their relationships!

This time, he told a HIGHlarious story about his Ocean's 11 co-star, Brad Pitt!

Georgie revealed that they constantly prank each other on set, but his favorite joke had to be when Brad turned an entire town against him:

"We were shooting Ocean's 12 in my hometown in Lake Como, and he had a flier sent around saying George only wants to be called by his character's name Danny Ocean, don't look him in the eyes. It got into the local paper. As you know, jokes don't translate at all, and they called me il divo, and said that I was treating the crew like s–t. When it got into the paper I came downstairs and Brad had the paper in his hand, and I said, 'You're mine from here on out.' Brad just said, 'Please don't harm my children.' Yeah, he's done some pretty rotten things."
